Cesium sulfate Usage And Synthesis

Description	Cesium sulfate is used for equilibrium density gradient centrifugation, one of the most useful tools for fractionation and characterization of macromolecules, such as DNA. Cesium sulfate can be used as catalyst, e.g. catalyst of cesium sulfate/vanadium pentoxide is used in abiabatic multibed reactors to lower inlet temperature and catalyst cesium sulfate/zeolite is used in a pilot plant scale process to synthesize 4-methyl thiazol.
